It is very important to have crushing equipment on your mining project as it helps in easy transportation of excavated minerals. Crushing equipment is particularly designed to break down hard rock matter, ore or gravel into convenient sizes for transportation. There are two broad types of crushing equipment—compressive crushers and impact crushers.
They are used in the mining of a number of materials including coal, oil, rock salt, diamonds, metals and iron. There are a number of crushers used in the mining industry. It is important however, to carefully pick a crusher that best fits the item you want to process.
To achieve the best results, it is imperative that you use the best crushers especially for processing your excavated minerals. We offer a range of industry-leading crushers for sale and lease.
Jaw Crushers are compressive crushers, they breakdown rock, ore or gravel between a fixed and a moving jaw. The fixed jaw is attached to the top of a pitman that has a reciprocating motion while the fixed jaw is immovable. When material is fed into the jaw crusher, the jaws compress large boulders into small pieces.
There are two types of gyratory crushers—the single toggle jaw crusher and the double toggle jaw crusher. The only difference between the two is the amount of toggle plates and shafts present in the jaw; the single toggle jaw crusher has one shaft and one toggle plate, while the double toggle jaw crusher has two shafts and two toggle plates.
Cone crushers are often used in the secondary, tertiary and quaternary crushing phases. A cone crusher consists of an oscillating shaft, a crushing cavity, an external fixed element and an internal movable element mounted on the oscillating shaft.
To optimize costs, it is recommended that cone crushers be choke fed, this means that the cavity needs to be full of as much material as possible.
Gyratory Crushers are also compressive crushers. They are often used in the primary crushing phase and less often in the secondary phase. A Gyratory crusher consists of an oscillating shaft, a crushing cavity, a bowl liner and a mantle.
Materials are crushed by the continuous compression that takes place in the crushing cavity. This type of crusher is equipped with a hydraulic setting adjustment system which enables the regulation in gradation of the crushed material.
Impact crushers are more versatile than compressive crushers as they can be used in any phase of the crushing process; however the features of impact crushers differ from those of compressive crushers. There are two types of impact crushers: horizontal shaft impact and vertical shaft impact.
The horizontal shaft impact crusher is used in primary, secondary and tertiary crushing phases. A Horizontal shaft impact crusher works by generating highly intensive impacts through the quick rotational movement of the hammers which are fixed to the rotor. The products of this impact crushing are then fragmented inside the crusher cavity which results in the production of fine particles.
The vertical shaft impact crusher, on the other hand, is used only in the last stage of crushing most especially when the required end products are needed to come in a cubical shape. The vertical shaft impact crusher operates like a centrifugal pump. It works by generating high speed in its cavity; materials which are fed through the centre of the rotor will be accelerated before being discharged through openings in the rotor periphery. The material is then crushed when it hits the outer body at high speed.
